VENTILA-TOR.

Application filed April 12, 19527. Serial No. 183,123.

Another object of the invention is the provision of a ventilator which includes novel form of shutter and means for pivotally mounting the shutters within the ventilator frame, so that the shutters may be adjusted, the shutters being separated by partitions which are shaped to conform to the shape of the shutters. I

Another object of the invention. is the provision of means for convenientlyand simultaneously adjusting the shutters to regulate the passage of air through the ventilator.

Another objectof the invention is the provision of aventilator which in addition to the above and other advantageous features, 1ncludes a frame which is constructed SO as to receive a SCIQGII.

lVith the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a fragmentary elevation showing the invention applied.

Figure 2 is a vertical sectional view showing the invention applied to a window sash and the latter mounted within a window frame.

Figure 3 is a section taken substantially on the line 33 of Figure 1.

Figure 4 is an enlarged section on the line 4.& of Figure 3.

Figure 5 is a section on the line 5+5 of Figure 4.

Figure 6 is a section on the line 66 of Figure 4.

Figure 7 is a fragmentary section taken on the line 77 of Figure 6.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates a ventilator frame or casing which may be arranged within a window frame,

or may form a part of a window sash. For. the purpose of securing the ventilator frame within a window sash, the sash which is indicated at 11 is supplied with an auxiliary rail 12 which is spaced from the usual sash rail 13. The stiles andrails of the sash are provided with the usual grooves 14 for receiving the edges of the window pane 15, the rail 12 being provided with a similar groove 14. The edges of the frame or casing 10 are provided with right angularly arranged flanges 16 which are received within the grooves 14-14 and are secured there.-

- in by any suitable means. The frame of the ventilator thus forms apart of the sash 11.

Pivotally mounted between the upper'and lower horizontal members 17' of the frame 10, as shown at 18, are shutters 19. These shut-ters'include arcuate walls 20 and end wings 21. Arranged between the shutters are partitions 22 whose outer edges are curved to conform to'the curvature of the walls 20, as shown at 23, so that the shutters may be adjusted pivotally to regulate the passage of air through the ventilator'andvto provide a proper it when the shutters are closed. Spaced from the end walls of the frame or casing 10 are supplemental walls 7 24 and 25 which have their outer edge portions curved as shown.

Extending from the wings 21 of the shut-. ters are pins or studs 26. These pins or studs extend upwardly through arcuate slots 27 provided in one of the horizontal walls of the casing or frame 10 and are attached to a rod 28 so that when the latter is moved longitudinally the shutters will be simultaneously adjusted.

In order to conveniently effect this adjustment one end of the rod 28 is toothed to provide a rack 29. This rack engages a pinion 30 which is mounted upon a shaft 31, the latter also having mounted thereon a pinion 32. This last mentioned pinion engages a toothed rack 33 carried at one end of a vertically movable rod 34. The rod.

extends downward through the frame or casing 10 and through the rail12 and is are provided with a flange 40 so as to proscreen 42. A unitary structure is thus provided. which may be carried by the sash which includes an adjustable ventilator for regulating the draft and a screen for pre venting the passage of insects. I

The invention is susceptible of various changes in its form proportions and minor details of construction and the right is here in reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is g 1. A ventilator comprising a casing open at its front and rear and having spaced arcuate slots in one of its horizontal walls, shutters mounted for pivotal movement between said walls concentric with said slots,

a rod extending longitudinally of the easing, pins extending through the arcuate slots and connecting the shutters and rod and means associated with the rod tomove the latter longitudinally to adjust the shutters.

2. A ventilator comprising a casing open at its front and rear and having spaced arcuate slots in one of its horizontal walls, shutters mounted for pivotal movement be tween said walls concentric with saidslots a rod extending longitudinally of the easing, pins extending through the arcuate slots and connecting the shutters and rod, a rod disposed at right angles to the first mentioned rod and means ope 'atively associated with said rods to move the first referred to rod longitudinally to adjust the shutters when the second mentioned rod is operated.

3. A ventilator comprising a casing open at its front and rear and having spaced arcuate slots in. one of its horizontal walls, shutters mounted for pivotal movement between said walls concentric with said slots, a rod extending longitudinally of the casing, pins extending through the arcuate slots and connecting the shutters and rod, a rod disposed at right angles to the first mentioned rod, rack barsat the ends of each rod and gearing connecting the rack bars to move the first referred to rod longitudinally to adjust the shutters when the secondmem tioned rod is operated.

4C. The combination with a window sash having a glass receiving groove,- of a bar extending across the sash and spaced from one end of said sash and also having a groove a ventilator frame, a flange'extend ing around the ventilatorfran'ie within the groove and means to secure the flange with-' in the groove. r

In testimony whereof I alfix my signature. Y JOHN LINZ.-
